1.“There is but one universal Church of the faithful, outside which no one at all is saved.” (Pope Innocent III, Fourth Lateran Council, 1215).

2. “We declare, say, define, and pronounce that it is absolutely necessary for the salvation of every human creature to be subject to the Roman Pontiff.” (Pope Boniface VIII, the Bull Unam Sanctam, 302.).

3.“The most Holy Roman Church firmly believes, professes and preaches that none of those existing outside the Catholic Church, not only pagans, but also Jews and heretics and schismatics, can have a share in life eternal; but that they will go into the eternal fire which was prepared for the devil and his angels, unless before death they are joined with Her; and that so important is the unity of this ecclesiastical body that only those remaining within this unity can profit by the sacraments of the Church unto salvation, and they alone can receive an eternal recompense for their fasts, their almsgivings, their other works of Christian piety and the duties of a Christian soldier. No one, let his almsgiving be as great as it may, no one, even if he pour out his blood for the Name of Christ, can be saved, unless he remain within the bosom and the unity of the Catholic Church.” (Pope Eugene IV, the Bull Cantate Domino, 1441.) – from the website Catholicism.org and “No Salvation outside the Church”: Link List)

Christ “established here on earth” only one Church and instituted it as a “visible and spiritual community”, that from its beginning and throughout the centuries has always existed and will always exist, and in which alone are found all the elements that Christ himself instituted. “This one Church of Christ, which we confess in the Creed as one, holy, catholic and apostolic.

This Church, constituted and organised in this world as a society, subsists in the Catholic Church, governed by the successor of Peter and the Bishops in communion with him”.The word “subsists” can only be attributed to the Catholic Church alone precisely because it refers to the mark of unity that we profess in the symbols of the faith (I believe... in the “one” Church); and this “one” Church subsists in the Catholic Church.-Responses to Some Questions Regarding certain Aspects of the Doctrine on the Church.(June 29, 2007)

'"It follows that these separated churches and Communities, though we believe they suffer from defects, are deprived neither of significance nor importance in the mystery of salvation. In fact the Spirit of Christ has not refrained from using them as instruments of salvation, whose value derives from that fullness of grace and of truth which has been entrusted to the Catholic Church..."'
